BACKGROUND: The goal of carotid artery stenting (CAS) is to decrease the stroke risk in patients with carotid stenosis. This procedure carries an immediate risk of stroke and death and many patients do not benefit from it, especially asymptomatic patients. Patient selection for carotid procedure who benefit from procedure and who is the procedure hazardous for is important. Remote ischemic stroke is known risk factor for stroke reccurence during surgery. The aim of our study was to determine the periprocedural complication risk (within 30 days after CAS) associated with carotid stenting (stroke, death) between patients with remote pre- procedural ischemic stroke and without it; to analyse periprocedural risk in other specific patient subgroups treated with CAS and to determine the impact of observed variables on all- cause mortality during long-term follow-up...

We investigated the role of oxidative stress-responsive kinase-1 (OSR1) and STE20 (sterile 20)/SPS1-related proline/alanine-rich kinase (SPAK), upstream regulators of the Na(+)-K(+)-2Cl(-) cotransporter (NKCC1)-essential for spermatogenesis-in mouse models of male fertility. Global OSR1(+/-) gene mutations, but not global SPAK(-/-) or Sertoli cell (SC)-specific OSR1 gene knockout (SC-OSR1(-/-)), cause subfertility with impaired sperm function and are associated with reduced abundance of phosphorylated (p)-NKCC1 but increased p-SPAK expression in testicular tissue and spermatozoa...

Cell volume homeostasis requires the dynamically regulated transport of ions across the plasmalemma. While the ensemble of ion transport proteins involved in cell volume regulation is well established, the molecular coordinators of their activities remain poorly characterized. We utilized a functional kinomics approach including a kinome-wide siRNA-phosphoproteomic screen, a high-content kinase inhibitor screen, and a kinase trapping-Orbitrap mass spectroscopy screen to systematically identify essential kinase regulators of KCC3 Thr(991)/Thr(1048) phosphorylation - a key signaling event in cell swelling-induced regulatory volume decrease (RVD)...

The complete genomic sequence of a new virus from cherry trees was determined. Its genome is 5857 nt long and resembles that of members of the genus Luteovirus in its genomic organization and nucleotide sequence. Based on the species demarcation criteria for luteoviruses, the virus represents a new luteovirus species. Furthermore, a 47-nt-long inverted repeat was found at the 3' end of its genome. The virus has been provisionally named cherry-associated luteovirus (ChALV) and is the fourth member of the family Luteoviridae reported to naturally infect woody plants...

BACKGROUND: Distal tubular sodium retention is a potent driver of hypertension, with the thiazide sensitive sodium-chloride cotransporter (NCC) a key player. The upstream modulators of NCC are unclear, but recent evidence has revealed the kinases 'with-no-lysine kinase 4' (WNK4) and 'STE20/SPS1-related, proline alanine-rich kinase' (SPAK) to be involved. The wider role of mineralocorticoids is poorly understood, but animal models implicate aldosterone as a potent regulator, possibly via effects on plasma potassium...

Previously, we reported that 6-(3,4-dihydro-1H-isoquinolin-2-yl)-N-(6-methylpyridin-2-yl) nicotinamide (DIMN) analogues inhibited the growth of prostate cancer cells as an anti-androgenic compound. In the present study, we evaluated cytotoxic effects of these DIMN derivatives and found that DIMN-26 most potently inhibited the proliferation of the LNCap-LN3 androgen-dependent and DU145 androgen-independent prostate cancer cells through induction of G2/M phase cell cycle arrest and subsequent apoptosis. The G2/M phase arrest was found due to increases in the activation of cdc2 (also known as cyclin-dependent kinase 1, CDK1)/cyclin B1 complex...

Characteristics of cirrhosis-associated cryptococcosis first diagnosed after death are not fully known. In a multicenter study, data generated as standard of care was systematically collected in 113 consecutive patients with cirrhosis and cryptococcosis followed for 80 patient-years. The diagnosis of cryptococcosis was first established after death in 15.9% (18/113) of the patients. Compared to cases diagnosed while alive, these patients had higher MELD score (33 vs. 22, P = .029) and higher rate of cryptococcemia (75...

The thiazide-sensitive Na-Cl cotransporter (NCC) is the major pathway for salt reabsorption in the mammalian distal convoluted tubule. NCC plays a key role in the regulation of blood pressure. Its inhibition with thiazides constitutes the primary baseline therapy for arterial hypertension. However, the thiazide-binding site in NCC is unknown. Mammals have only one gene encoding for NCC. The eel, however, contains a duplicate gene. NCCα is an ortholog of mammalian NCC and is expressed in the kidney. NCCβ is present in the apical membrane of the rectum...

Sterile 20/SPS1-related proline/alanine-rich kinase (SPAK) can stimulate production of proinflammatory cytokines and interact with inflammation-related molecules. However, it has yet to be determined whether SPAK plays a pathophysiological role in the complicated pathological mechanisms of IgA nephropathy (IgAN), which is mainly characterized by mesangial cell (MC) proliferation and is the most common form of glomerulonephritis. In the present study, we examined the pathophysiological role of SPAK in IgAN using a mouse model and cell models...

KEY POINTS: High dietary potassium (K(+) ) intake dephosphorylates and inactivates the NaCl cotransporter (NCC) in the renal distal convoluted tubule (DCT). Using several ex vivo models, we show that physiological changes in extracellular K(+) , similar to those occurring after a K(+) rich diet, are sufficient to promote a very rapid dephosphorylation of NCC in native DCT cells. Although the increase of NCC phosphorylation upon decreased extracellular K(+) appears to depend on cellular Cl(-) fluxes, the rapid NCC dephosphorylation in response to increased extracellular K(+) is not Cl(-) -dependent...

BACKGROUND: Brief interventions in primary healthcare are cost-effective in reducing drinking problems but poorly implemented in routine practice. Although evidence about implementing brief interventions is growing, knowledge is limited with regard to impact of initial role security and therapeutic commitment on brief intervention implementation. METHODS: In a cluster randomised factorial trial, 120 primary healthcare units (PHCUs) were randomised to eight groups: care as usual, training and support, financial reimbursement, and the opportunity to refer patients to an internet-based brief intervention (e-BI); paired combinations of these three strategies, and all three strategies combined...

Distal tubular sodium retention is a potent driver of hypertension, and the thiazide-sensitive sodium-chloride cotransporter (NCC) has a key role in this process. In humans, factors regulating NCC are unclear, but in animal models, aldosterone is a potent regulator, possibly via effects on plasma potassium. We studied the effects of the mineralocorticoid fludrocortisone on the abundance of NCC and its phosphorylated form (pNCC) as well as WNK lysine deficient protein kinase 4 (WNK4) and STE20/SPS1-related, proline alanine-rich kinase (SPAK) in human urinary exosomes...

PURPOSE OF REVIEW: Abundant evidence supports that the NaCl cotransporter (NCC) activity is tightly regulated by the with-no-lysine (WNK) kinases. Here, we summarize the data regarding NCC regulation by WNKs, with a particular emphasis on WNK4. RECENT FINDINGS: Several studies involving in-vivo and in-vitro models have provided paradoxical data regarding WNK4 regulation of the NCC. Although some studies show that WNK4 can activate the NCC, other equally compelling studies show that WNK4 inhibits the NCC...
